Scientist Caspian Trueway is excited about his first job with TerraFCorp, figuring out where to drill for water on TF-21, nicknamed Hades for its rough terrain. When he gets there he meets Robin, an old hand at terraforming who takes Caspian under his wing. They find out they have more in common than their jobs, and they're just settling in when a saboteur starts wreaking havoc with their water supplies and equipment. When the attacks start spilling over to the people, they realize things are getting out of hand. Together they work to find the saboteur, but can their new relationship take the strain?
